I trained as a marine scientist at the University of San Diego (B.A. and M.S. Marine Science) and The Australian National University, obtaining a PhD in isotope geochemistry in 2001. I then went to the Center for Accelerator Mass Spectrometry at Lawrence Livermore National Laboratory to learn radiocarbon preparation and measurements using AMS. In 2004 I moved to the Chemistry, Biology and Nuclear Science Division at LLNL and developed isotopic measurements and maps using the CAMECA nanoSIMS. In 2006 I returned to Australia to take up a research Fellow position as the head of the newly refurbished Radiocarbon Dating Laboratory at the Research School of Earth Sciences, The Australian National University. Since 2010 I have been a Fellow at the Research School of Earth Sciences. My research interests include radiocarbon dating, using radiocarbon as a tracer for the carbon cycle, developing proxy records of marine environment using trace element and isotopic records from biogenic archives and examining past environmental change to help understand our future climate.

Coral geochemistry in a changing Ocean. Using Porites coral cores examine elemental and isotopic proxies under changing ocean acidification from a natural pH gradient in PNG.
Deep Sea Corals as climate archives. Utilize elemental, isotopic and radiometric proxies trapped in deep sea coral skeletons to examine past climate.
Australian Lungfish ecology. Utilize isotopic proxies to understand the changing river ecology that is putting the Australian Lungfish under threat.
Novel Uses of Radiocarbon in Environmental Studies. Utilize the state of the art AMS and radiocarbon preparation labs at RSES to investigate carbon cycle studies.
